REVERSIBLE LATCH.

SPECIFICATION forming part of Letters Patent No. 341,805, dated May 11, 1886.

Application filed June 3, Serial No. 167,701. (No modehl Patented in England January I, 1885, No. 9.

To aZZ whom it may concern:

Be it known that I, JAMES HILL, a subject of the Queen of Great Britain, residing at 100 Queen Victoria Street, London, E. (3., have invented certain new and useful Improvements in Reversible Latches, (for which I have obtained Letters Patent in Great Britain, dated January 1, 1885, and numbered 9;) and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

This invention has relation to that class of combined locks and latches generally known as flanged-rim locks, the lock and latch mechanism being incased in a suitable casing, and the latter fitted into aflanged framehaving holes in its face-plate or fore end for the passage of the bolt and latch.

The object of my invention is to provide a reversible lock and latch; and it consists in the combination, with a flanged frame or rim having in its fore end or face-plate bolt and latch holes of equal size and similar form, of a combined lock and latch, in which the latch is beveled, and so constructed that when ontot' the flanged rim it may be revolved or turned, and accordingly rendered reversible, for use as a right or left hand latch.

Referring to the accompanying drawings, Figure 1 is a front view of the molded frame or flanged rim; Fig. 2, a vertical transverse section of the same; Fig. 3, a side view of the combined lock and latch; Fig. 4, a front view of the lock and molded frame combined; Fig. 5, a fore end view of the molded case, and Fig. (5 a back view of the lock and frame combined.

A designates the molded frame or rim, consisting of a casting of rectangular form, having an open flanged recess, B, of a size and shape to receive the lock-case E, which, when in place, lies behind and against the flanges B and inside or back of the face-plate. The

latter is. formed with two equalsized and similarly-shaped holes, D D for the passage of the latch and bolt 0 C", respectively.

E designates the combined lock and latch case, of any desired character, but of'a size and shape to exactly fill the space provided for its reception in the molded frame.

The latch and bolt are of equal size and shape in cross-section, the head of the bolt being of rectangular form. Thelatch O is, however, provided with a beveled head, or is otherwise so constructed that when the lock is out of the molded frame the latch or latchhead may be revolved so as to bring the beveled portion to either side, and thus render the latch either a right or left hand latch. When the lock is in place in the molded frame, the latch is prevented from turning by the face plate of the frame, and hence operates as an ordinary beveled latch.

By reason of the construction of the latch and the shape and size of the bolt and latch and of the holes D D it is obvious that the lock may be reversed and inverted, so as to adapt it to various requirements.

Having described my invention, I clai m In flanged-rim locks and latches, the combination, with the molded or flanged frame A, having a face-plate with equalsized and similarly-shaped bolt-holes D I)", of the combined lock and latch comprising the loclc-case'and the lock and latch bolts 0 O, of equal size and shape in cross-section, said size and shape corresponding with the holes D D", the latch 0 being beveled, and constructed and adapted to be reversed, whereby the lock is made reversible in the frame, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 15th day of May, 1885.

JAMES HILL.
